lMPROVED APPARATUS FOR SEPARATING GREASY Specification forming part of Letters Patent No. 48,559, dated July 4, 1365.

To all whom it 'may concern', W

Be it known that I, DAVID'H. KAUFMAN, of Kolroinmin the county of Howard and State of Indiana, haveinvented anew and useful Iniproveinentin Apparatus for Separating Grease from Slush; andlowing to bea full, clear, and exact description of the nature, construction, and operation ot'4 the same, reference being had to the annexed drawings, makingpart4 ot' this spcciticatiolnin Y which- Figui-ce1 is a plan view, and Fig. 2 .a verti-v cal longitudinal sccton.- i

Similar letters ot' reference indicate corresponding parts iu the two figures.

Theobjectot this improvement is to-separate the contents of the `tanks in which-the greasy cal of the slaughter-house is rendered, so as tdcollect the` grease which iioats upon the To enable one skill( d in the branch et' industry to which inyinventiou rel'ers to construct and use the. same, I will proceed to del scribe it. i

A is a vat, which receives the conte-nts ot the lard-vat or rel'idering-tank after they havc'been subjected to the action ot' hea-t therein.

B is a. gate at the end of the vat, which is provided' with springs C and a bearer, and' with gum packing to in alre it watertight. "lhe 'gate is raised and lowered by a crank, D, pinalid rack F, so as to regulatethe amount ion E iows out to the inclined grating G and which board H,theformer ot' which arrests any coarse I do hereby declare. the folfatty matter which may have' passed from thei `'rendering-tank before it has been perfectly cooked. The latter or board II discharges the fluid in to the smaller chamber I of the lower-l` vat,in` whichthe fatty matter, rising to .the top by its le vity,-is retained, while the wateiat thcbcttom passes through the opening J, which is regulated by the gat-e K,i`nto the larger rc' ceptacle L, from whence it runs oit' by either of the openings M M M, as may be required.- By means of this apparatus a'great deallof handling is saved, anda large percentage of grease recovered, vas the fatty fluid collects in the chamber I, from which it is removed from time to time, while t-he slush passes oft' continuously to the receptacle adapted to receive.it.`

Having thus described myinvention, what I claim herein as new, and desire to secure by Letters Patent,`is 1. The combined apparatus' shown and described, consisting ot" the upper vat, with its 'adjusting-gate, the grated incline, and the divided vat I L, with their communicating openlng. 2. The vat, with its respective chambers I L communicating atv or near the bottom, so as to act usa separator by allowingthe lower or watery fluid to pass out of the chamber which retains the grease.
